So most of you recognize, if we switch back to the notes, that they do have a negative electron affinity.

看来大部人都想到了，如果你翻翻讲义的话，它们的电子亲和能确实是负的。

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?

那么，你认为稀有气体的电子亲和能，应该是一个高的正值，一个低的正值，还是一个负值？

Traditional fuel cells work by using a catalytic material to oxidise a fuel, such as hydrogen, turning it into a positively charged ion and a negative electron.

传统的燃料电池使用催化材料来氧化燃料，比如氢气，使之转变为一个带正电的离子与一个电子。
